A power supply is an electrical device that provides power to an electrical load. It converts electrical energy from one form to another. Example: Converts AC (Alternating Current) from the wall into DC (Direct Current) used by computers. --- Slide 3: Types of Power Supply 1. AC to DC Power Supply Most common in electronics. 2. DC to DC Converter Used in laptops, mobile phones. 3. Uninterruptible Power Supply (UPS) Backup power source. 4. Programmable Power Supply Used for testing and development. Slide 4: Key Components Transformer: Changes voltage level. Rectifier: Converts AC to DC. Filter: Removes ripples in output. Regulator: Maintains constant voltage. Slide 5: Power Supply in Computers Converts AC to DC for internal components. Supplies different voltages: +12V, +5V, +3.3V. Called SMPS (Switched-Mode Power Supply). Slide 6: Applications Computers & laptops Televisions Mobile phone chargers Industrial machines Medical devi Slide 7: Safety Tips Do not open power supplies — high voltage! Ensure proper ventilation. Avoid overloading the circuit. Use correct fuse rating Slide 8: Conclusion Power supplies are essential for modern electronics. Choosing the right type ensures safe and efficient operation. Always follow safety precautions when handling power equipment. Slide 9: Questions Any questions? Thank you for your attention!
